Mad Dog Bites Hippo
In the following game, GM Joel Benjamin tries out a flexible hippopotamus set-up against IM Marc Esserman's aggressive "mad dog" formation, "blunting White's Bishop on c4" with e6 (as the title of Colin McNab's chapter on the line in Dangerous Weapons: The Pirc and Modern would have it.) But there is something that does not love a wall, and the Mad Dog Bishop eventually bites through to deal a deadly blow to Benjamin's hippo.
Marc Esserman - Joel Benjamin [B06]
Marshall CC New York International/New York, NY USA (4) 2010
Blunting the dangerous diagonal of the "mad dog" White Bishop. This is very much what you might expect from Benjamin, who is known for a similar set-up against the Classical variation. Both lines with an early Black ...e6 are discussed in "Dangerous Weapons: The Pirc and Modern" (Everyman 2009).
A sensible waiting move, to avoid being hit with a forceful ...d5 advance later. Esserman eventually finds a way to open the Bishop's diagonal.
This seems, in retrospect, to be a minor inaccuracy that allows Esserman to set up an annoying Queen and Bishop battery that discourages castling by Black. Instead, 5... Ne7 is given by Colin McNab in Dangerous Weapons: The Pirc and Modern, when White's standard plan is to bring his Knight from b1 to g3 and try to build toward an eventual kingside attack: 6.

It's debatable who has gained the most from the Bishop's adventure to g5, since ...h6 is a standard part of the hippo tabiya. But I think this flexible set-up is good for White, since it is now very difficult for Black to castle without dropping the h-pawn. Esserman loves to keep his opponent's King in the center of the board, especially when he plays the Smith-Morra.
Black hopes to label the d5 pawn a target, but opening the e-file before the King has castled always feels dangerous.
Black decides to "castle by hand" since O-O drops the h-pawn. Alternately, 13... Qd7 14. a4
Now Esserman is finally able to liberate his "mad dog" Bishop leading to a swift finish.
The Black Queen is lost, and the computer gives a forced mate in 11 moves. A tremendous attacking game from the ever-creative Mark Esserman. Benjamin's early e6 tried to fence out the Bishop at c4, but it eventually broke through with a vengeance.
